Recognized dog breed group by American Kennel Club. Terrier group includes 28 breeds developed to hunt vermin and to dig them from their burrows or lairs.

Terriers are known for their feisty and energetic personalities, which is why so many people associate them with these characteristics. Vermin, particularly rats and mice, are hunted and killed by these dogs, and they are also used to protect their family’s home or barn. Terrier breeds range from the Norfolk, Cairn, or West Highland White Terrier, which are small and lively, to the Airedale Terrier, which are big and strong. Because these dogs are strong-willed, determination is required on the part of their owners, and they require extra grooming known as “stripping” in order to maintain their distinctive appearance.
